T 0 all whom it may concern:

Be it known that I, HIRAM M. HANMoRn', a

citizen of the United States, and a residentof Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Composition for Bricks for Buildchanging the character of the composition;

but theproportions which I prefer are as follows, by weight: diatomaceous earth, sixtyfive parts; calcic oxid, thirty parts; aluminium clay, five parts.

For the manufacture of composition the 'several ingredients are ground to powder and after having been-thoroughly mixed together suflicientwater is added and mixed with them to form a mass of suflicient consistency to be molded by an ordinary brick-machine or in kflullllllwn any manner practicable in the manufacture of 25 bricks from clay. The bricks thus molded are dried in a kiln or in the sun or otherwise in the open air and when thoroughly dried are ready without firing for use for all purposes in which ordinary bricks are used. They will withstand a much greater heat.- They have great tensile strength and fire-resisting properties.'

weigh less than half the ordinary brick and What I claim as my invention isi 35 Acomposition for bricks for building purposes comprising diatomaceous earth, calcic oxid and aluminium clay in which the calcic oxid is in excess of the clay and the diatorna ceous earth isin excess of the ealcic oxid. 4
